Hi, Thank you for posting on HCM From your description your son is presenting with a kidney infection most probably pyelonephritis. The type of pain is usually nephritic colic and the usual pain remedy would not work. Your son will require an antispasmodic and definitive cure. First your doctor will need to do a urine analysis and culture to determine the kind of bacteria involved, do blood work up and probably a kidney ultrasound. Presence of ketones in urine might be physiologic or due to another illness such as diabetes. So fasting blood sugar test is recommended. Other possible causes of protein in urine such as nephritic syndrome, nephrotic syndrome etc need to be ruled out by your doctor. Hope this helps
